I haven't seen another thread about the rivalry between these two pairs teams aside from discussion in Canadian Pairs thread topics.
But I think the development of these two teams and the back-and-forth rivalry has been very interesting. I thought both teams were strong when they came into prominence on the pairs scene a couple of seasons ago. At that point, I was more impressed by M-T/M. However. last year at Canadian Nationals, Meagan and Eric stole my heart.
I think Julie Marcotte is a genius, and she has obviously helped the growth and improvement of a number of pairs teams, including the former Takahashi/ Tran pairing, Duhamel/ Radford, and this season, Castelli/ Shnapir of the U.S.
Perhaps D/R are stronger technically than M-T/M. But both teams are looking very good this season. The results at 4CCs between them was interesting, and has heated up their rivalry for Worlds in March. M-T/M have a dynamite of a well-choreographed long program, so it will be an intense and interesting battle for the bronze.
I think the two top Canadian teams are much stronger than the second and third Russian teams, and also fresher and more interesting than Pang/ Tong. Of course Berton/ Hotarek will also be in the mix at Worlds, but I still think the Canadians are better overall than those challenging for the bronze.
